To all whom it may concern:

Be it known that I, CHARLESZH. Binn- CHARD, a citizen of the United States, and

' an apparatus to be used in conjunction with a basin of water for automatically regulating the time of immersion of eggs, or the like, in boiling water; and the Object of my invention is to provide simple meanswhereby the automatic mechanism may be set tooperateat various )eriods of time.

To the a ove pur oses, my invention consists in certain nove features of construction and arrangement of parts, which will be here inafter more fully set forth, ointed out in the claims, and illustrated in t e accompanying drawings, in which Figure 1 is a front elevation of an egg boiler of my improved construction; Fig. 2 is a side elevation of the apparatus, with par-ts brokenaway, in order to more clearlyillus" trate the same; Fig. 3 is an enlarged detail section taken on the line 3-3 of Fig. l Fi 4 is a front elevation of the housing inwhicli the clock mechanism is located, and with the front plate of the housing removed; Fig. 5 is an elevation of the housing seen in Fig. 4,

and with the lower portion of said housing in vertical section; Fig. 6 is a vertical section taken on the line 66 of Fig. 5.

end of a chain or cable 4, which passes grooved pulleyfi fixed to t Referring by numerals to the accom anying drawings :-1 designates a vertical y disposed tube, which is supported in any suitable manner adjacent a water receptacle 2,

which may be heated in any suitable manner to boil the water therein. Arranged for vertical movement within the tube 1 is a weight 3, to the upper end of which is secured one I Fixed one of the links of the chain 4, ad-

jacent the :weight 3,-is a block 8, having a beveled "front face 9, and a straight rear face 10. 1

Detachably fixed in any suitable manner a to the upper end of the tube 1 is a housing 1 1,

provided with a removable front late 12, and with ,a partition 13, located a s ort disterms to the rear of said front plate. Journaled for rotation in the center of this hous ing is a shaft 14, which is driven by an ordinary spiral spring 15, and the rotary motion of tins shalt isgoverned by an ordinary e s capem'ent 16 connected to said shaft by a suitable train of gearing '17, and there being a pendulum 18 arranged in the usual manner onthe allet'shaft 19 of the escapement.

Rigi 1y fixed in any suitable manner to the front end of the shaft 14, in front of the plate 12, is a'segmental plate 20, and formed adjacent the'edge thereof is a series of apertures 21, which are located at equal distances apart, and said apertures being consecutively numbered. Arran ed immediately against the rear. face'of this plate 20 is an arm 22, whichcarries a pin 23, adapted to enter any one ofv the a ertures 21; and said arm projects beyon .the face of the housing, and there being '9. lug or sto 24 formed on the edge of the housing against which the arm engages when moved downward, as is the case when the apparatus is set for use. The inner end of the arm 22 is loosely arranged on a hub 25, fixed on the center of the plate 12, and located on said hub and interposed between the plate and the arm is an expansive coil spring 26, which normally maintains the armagainst the segmental plate 20.

Fulcrumed on a pin 27, which is seated in ing 29formed in thebottom of the housing 11, and said lower end of the lever normally occupying aposition across the up or end of the opening 5 m the tube 1, and irectly in the ath of travel of the outer portion of the bloc 8. A spring 30 bears against one side of this lever 28 to hold the same in proper osition, and the upper end of said lever is bent horizontally forward, as designated by 31, and said forwardly bent end rojects through a slot 32 formed through t e front plate 12, and which slot is concentric with the pivot pin 27.

To set my improved apparatus for use, the

operator engages the outer'end of the arm 22, and moves the same rearwardly so as to disen agethe pin 23 from the aperture in which it as been positioned, and then rotates the arm in either direction so as to bring the pin 23 into the aperture corres onding to the time of the maintenance 0 the basket or container 7 in the boiling water. In the present instance, it is assumed that the apparatus is used as an egg boiler, and the spaces between the apertures 21, which latter are numbered consecutively from 1 to 6, represent periods of one minute each. The engagement of the pin 23 in one of the apertures locks the arm 22 to the plate 20, and when the arm 22 is now moved downwardly until it engages against the stop 24, the segmental plate 20 will be co'rres' ondingly moved, and the shaft 14 on whic 1 said plate 20 is fixed will be partially rotated,

thus partially winding andstoring power in the spring 15. Just prior to, or immediately after the rotation of the-shaft 14, the basket or container 7 containing the eggs to be boiled is moved downward until submerged.

in the boiling water within the receptacle 2,

and this movement elevates the weight 3,'

and brings the block 8 into a position-in front of the'lower end of the lever 28, withthe straight rear face 10 of said block enga ingv the lower end of said lever. The c ock mechanism, comprising the trainof gearing 17 and escapement 16, now operates in the usual manner, owin to the power stored in the spring 15, and .t e motion of said mechanism is controlled by the endulum 18.- The shaft 14 is slowly rotated by the clock mechanism, and the 'plate'20 and arm 22 are moved together on saidshaft 14; and, owing to the size of the segmentalplate 20 and the arrangement of the apertures 21 therein, the left hand edge of said plate 20 will engage the forwardly bent end 31 of the lever 28 at the expiration of the time for which the apparatus has been set; and, as said plate 20 ears against the bent end 31 of the lever,

the lower end thereof will be elevated, thus releasing the block 8, which permits the weight 3 to drop; and, as a result, the basket 7 is drawn out of the boiling water and elevated.

When the apparatus is reset for use, the arm 22 is moved downward until it engages against the lug 24, which movement rewinds the spring 15 and stores power therein; and thus said spring is rewound each time the ap aratus is set for use.

y apparatus can be advantageously applied for various uses, although it is articu- -arly adapted for use as an egg boi er; and said apparatus is easily adjusted and set for use, comprises a minimum number of parts, and is very accurate and efiicient in use.
